FERC-725G (DLO in RD23-4-000), Mandatory Reliability Standards for the Bulk-Power System: PRC Rel Stds.

RD20-1. Reliability Standard PRC-006-NPCC-2 establishes consistent and coordinated requirements for the design, implementation, and analysis of automatic underfrequency load shedding (UFLS) programs among all NPCC applicable entities. These requirements are more stringent and specific than the NERC continent-wide UFLS Reliability Standard, PRC-006-3, and were established such that the declining frequency is arrested and recovered in accordance with NPCC performance requirements. NPCC revised currently effective Regional Reliability Standard PRC-006-NPCC-1 to remove redundancies with the Reliability Standard PRC-006-3, clarify obligations for registered entities, improve communication of island boundaries to affected registered entities, and provide entities with the flexibility to calculate net load shed for UFLS in certain situations. RM16-22: Reliability Standard PRC-027-1: The purpose of proposed Reliability Standard PRC-027-1 is to maintain the coordination of Protection Systems installed to detect and isolate Faults on Bulk Electric System (BES) Elements, such that those Protection Systems operate in the intended sequence during Faults. RM16-20: Reliability Standard PRC-012-2 is to supersede “pending” Reliability Standards PRC-012-1, PRC-013-1, and PRC-014-1 and to retire and replace currently-effective Reliability Standards PRC-015-1 and PRC-016-1. Reliability Standard PRC-012-2 represents substantial improvements over these Reliability Standards because it streamlines and consolidates existing requirements; corrects the applicability of previously unapproved Reliability Standards; and implements a continent-wide RAS review program.
